hi, i got a 450 se, checked the plugs, and wires, changed the cap'n rotor, ran beutifuly, but after about 2 weeks, its now sputtering, backfiring, no power, and fuel is massively leaking from the 4th cylinder exhaust manifold right where the manifold meets the block. changed the injector and no effect. all that is left that i know of is the computer which ive found from 1500 to 700 dollars, the cold start valve, or the trigger points. please help.
as well, the fuel just seems to be pumping out the exhaust right where it meets the block, but no cracks. just a bad gasket. but what could be making it do this. keep in mind this doesnt have cats or o2 sensors or too much of anything.
